1. Baby chickens, like all baby birds, require a constant source of food. As chick grow, more
energy is required for daily activities, and their food requirements increase. The following
data table reports the average food eaten by a group of 10 chickens over a 5-day period.

Questions
1. Identify the independent and dependent
variables.
2. How much grain will the chicks eat on day 6?
3. On day 7?
4. What type of relation does the graph
represent?
2. The data below summarizes the results of a scientific experiment on the effects of a growth
hormone (gibberellic acid) on plant height. A 0.1 molar solution was used in all experiments.

1. Identify the independent and

2. Estimate the plant height at 10 mL
gibberellic acid.
3. Estimate the plant height at 25
mL?=.

4. Explain why the plant height at 60
mL is not consistent with the rest of
the data.
3. A team of scientists wanted to test the effects of temperature on the germination rate of pinto
beans. They placed three sets of 100 pinto bean seeds in temperature controlled chambers:
Chamber A was set at 15o C, chamber B at 20oC, and chamber C at 25oC. Their results are
shown in Table 1 below:

Questions
1. Identify the independent and
dependent variables.
2. Compare and contrast the
growth rate of pinto beans at the
different temperatures.
3. Summarize the experimental
results.
